Definitions
- the present invention relates to information handling systems. More specifically, embodiments of the invention relate to enhancing ground bounce immunity of cables such as USB type-C cables.
- An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information.
- information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated.
- the variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications.
- information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
- USB universal serial bus
- USB Type-C USB Type-C
- USB 3.1 defines a limit on ground (GND) bounce as well as voltage drop on the various signal paths including the ground signal paths due to cable resistance which often requires a high power cable and or the use of large diameter wires for the ground lines.
- GND ground
- ground bounce immunity is enhanced by making use of alternate modes of operation of cables conforming to the USB 3.1 specification to achieve a higher power over a cable that conforms to the USB 3.1 voltage drop specification requirements on the ground signal paths when the cable is operating at normal power levels (i.e., at a power level supported by the USB 3.1 specification).
- a cable with 3 Amps of current can have 0.25V of I*R drop on the GND return signal paths.
- An electronic marker (E-marker) in this cable identifies the cable as having a 3 Amp current limit.
- the E-marker can identify availability of an alternate mode of operation if a host and a device coupled to the other end of the cable each support changing a control signal path (e.g., a configuration channel (CC) signal path) reference voltage.
- CC signal path communication is briefly suspended, the USB port controllers in the Host, cable, and device all change their reference voltage and increase the voltage swing on CC signal path, then resume communication in this new mode of operation.
- a higher current e.g., 4.2 Amps of current
- the I*R voltage drop on the ground signal paths is now 0.35V. Because the voltage swing and reference voltage on control signal path (e.g., the CC signal path) has increased, the control signal path can also accommodate 0.35V of GND bounce with no disruption in control communication.
- the negotiation of the higher power mode of operation is only performed when a particular manufacturer host system, docking cable of the particular manufacturer and I/O device of the particular manufacturer are connected. In certain embodiments, the negotiation of the higher power mode of operation prevents other manufacturer's devices from accessing the higher power when connected to the particular manufacturer's power delivery devices.
- FIG. 1 shows a general illustration of components of an information handling system as implemented in the system and method of the present invention.
- FIG. 2 shows a block diagram of an environment for enhancing ground bounce immunity of cables.
- FIG. 3 shows a flow chart of a ground bounce immunity enhance operation.
- aspects of this disclosure include a recognition that the communication of the configuration channel (CC) signal path of USB Type-C interface is normally 1.1V peak to peak, and is not normally tolerant to higher than 0.25V of GND bounce.
- Cables that support 60 Watts (via e.g., 20V and 3 Amps) with 0.25V of I*R voltage drop on GND wires can be configured with acceptable cable bundle diameter and flexibility. For example, when a cable bundle is 4.8 mm in diameter, a strain relief collar can be provided which maintain a 6.5 mm outside Z dimension. When a USB Type-C plug with a 6.5 mm Z dimension is attached to a tablet, the tablet and cable can lay on a flat table without interference.
- the connector when the Z dimension of the USB Type-C plug is larger than 6.5 mm, the connector will cause the tablet to lift off of the resting surface and the weight of the tablet bears down on the Type-C plug. This force can cause reliability and user satisfaction issues.
- workstations which have higher power requirements (e.g., 90 Watts or 130 Watts) would require a larger diameter cable bundle (e.g., a cable bundle having 7.6 mm diameter). Such a larger diameter cable bundle is likely not acceptable from a usability perspective and might not even fit into an over mold of standard USB Type-C plug which 6.5 mm thick.
- aspects of this disclosure include a recognition that it would be desirable to provide a cable bundle carry 130 Watts of power, is acceptable for usability, and can fit into the Type-C plug over mold housing.
- an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes.
- an information handling system may be a personal computer, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price.
- the information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory.
- FIG. 1 is a generalized illustration of an information handling system 100 that can be used to implement the system and method of the present invention.
- the information handling system 100 includes a processor (e.g., central processor unit or “CPU”) 102 , input/output (I/O) devices 104 , such as a display, a keyboard, a mouse, and associated controllers, a hard drive or disk storage 106 , and various other subsystems 108 .
- the information handling system 100 also includes network port 110 operable to connect to a network 140 , which is likewise accessible by a service provider server 142 .
- the information handling system 100 likewise includes system memory 112 , which is interconnected to the foregoing via one or more buses 114 .
- System memory 112 further comprises operating system (OS) 116 and in various embodiments may also comprise active cable control module 118 .
- OS operating system
- I/O devices 104 of the information handling system 100 comprise an integrated I/O controller 150 as well as an integrated I/O connector 152 .
- the integrated I/O controller 150 comprises a Thunderbolt 3 type integrated I/O controller,
- the integrated I/O connector comprises a USB Type-C connector.
- a multi-modal cable 154 may be coupled to the connector 152 . Additionally, in certain embodiments the multi-modal cable 154 may be coupled with an I/O connection device 156 such as a docking station.
- the multi-modal cable 154 provides enhanced ground bounce immunity.
- ground bounce immunity may be defined as a power level above which communication on the cable is immune to ground bounce (i.e., where a transmission voltage appears as less than a local ground potential). More specifically, in certain embodiments, ground bounce immunity is enhanced by making use of alternate modes of operation of cables conforming to the USB 3.1 specification to achieve a higher power over a cable that conforms to the USB 3.1 voltage drop specification requirements on the ground signal paths when the cable is operating at normal power levels (i.e., at a power level supported by the USB 3.1 specification). For example, according to the USB 3.1 specification, a cable with 3 Amps of current can have 0.25V of I*R drop on the GND return signal paths.
- An E-marker in this cable identifies the cable as having a 3 Amp current limit.
- the E-marker can identify, availability of an alternate mode of operation if a host and a device coupled to the other end of the cable each support changing a control signal path (e.g., a configuration channel (CC) signal path) reference voltage.
- CC signal path communication is briefly suspended, the USB port controllers in the host, cable, and device all change their reference voltage and increase the voltage swing on CC signal path, then resume communication in this new mode of operation.
- a higher current e.g., 4.2 Amps of current
- the PR voltage drop on the ground signal paths is now 0.35V. Because the voltage swing and reference voltage on control signal path (e.g., the CC signal path) has increased, the control signal path can also accommodate 0.35V of GIN bounce with no disruption in control communication.
- ground bounce immunity is enhanced by making use of alternate modes of operation of USB3.1 type cables and standard use USB3.1 power delivery negotiation protocol to allow a host and end device to negotiate higher power than what would normally conform to the USB 3.1 Specification.
- the host might comprise a work station type laptop requiring 130 Watts power.
- the USB 3.1 specification might have a maximum supported power limit of 100 Watts. This negotiation is only performed with systems that can safely operate in a higher power mode of operation (e.g., a 130 Watts mode of operation) and I/O systems (e.g., docking stations) that can safely deliver this power.
- the negotiation of the higher power mode of operation enables the diameter of the cable to be minimized when compared to the diameter that would be required without use of the negotiation operation. For example, with certain cables, the diameter of the wires included within the cable would need to be increased to accommodate 4.2 Amps of current with 0.25V of I*R voltage drop on the ground signal paths. Such an increased diameter would make the cable less flexible, and the diameter of the bundle larger. Additionally, this negotiation of the higher power mode of operation enables a cable bundle that can fit properly with an over mold housing of a USB Type-C plug.
- FIG. 2 is a block diagram of an environment 200 for enhancing ground bounce immunity of cables. More specifically, the environment 200 includes an information handling system 210 (which may include some or all of the elements of information handling system 100 ) and a power adapter 212 . The environment 200 also includes a ground bounce enhanced cable 220 (which may include some or all of the elements of multi-modal cable 154 ). In certain embodiments the ground bounce enhanced cable 220 conforms to some or all of the portions of a USB Type-C cable.
- the ground bounce enhanced cable 220 includes a power signal path (VBUS), a ground signal path (GND) and a configuration channel signal path (CC).
- ground bounce immunity is enhanced by making use of alternate modes of operation of cables conforming to the USB 3.1 specification to achieve a higher power over a cable that conforms to the USB 3.1 voltage drop specification requirements on the ground signal paths when the cable is operating at normal power levels (i.e., at a power level supported by the USB 3.1 specification).
- a cable with 3 Amps of current can have 0.25V of I*R drop on the GND return signal paths.
- the operation 300 begins at step 310 when the cable is first connected between an information handling system and an adapter.
- an E-marker in the cable identifies the cable as having a 3 Amp current limit.
- the operation 300 determines whether the adapter 212 and the information handling system 210 are both capable of generating and receiving a higher current (i.e., of operating in an alternate higher power mode of operation).
- the alternate higher power mode of operation involves changing a control signal path (e.g., a configuration channel (CC) signal path) reference voltage. If either the information handing system 210 or the power adapter 212 are not capable of operating in an alternate higher power mode of operation then the operation 300 completes.
- CC configuration channel
- the E-marker identifies the availability of the alternate higher power mode of operation.
- communication on the CC signal path is briefly suspended and at step 332 the power adapter 212 and the information handling system 210 enter into the alternate higher power mode of operation.
- USB port controllers (not shown) in the information handling system 210 , the cable 220 and the power adapter 212 all change their reference voltage and increase the voltage swing on the CC signal path.
- the information handling system 210 and the power adapter 212 resume communication using the new mode of operation.
- ground bounce immunity is enhanced by making use of alternate modes of operation of USB3.1 type cables and standard use USB3.1 power delivery negotiation protocol to allow a host (e.g., an information handling system) and an end device (e.g., a power adapter or other type of I/O device such as a docking station) to negotiate higher power than what would normally conform to the USB 3.1 Specification.
- a host e.g., an information handling system
- an end device e.g., a power adapter or other type of I/O device such as a docking station
- the host might comprise a work station type laptop requiring 130 Watts power.
- the USB 3.1 specification might have a maximum supported power limit of 100 Watts. This negotiation is only performed with systems that can safely operate in a higher power mode of operation a 130 Watts mode of operation) and I/O systems (e.g., docking stations) that can safely deliver this power.
- the negotiation of the higher power mode of operation is only performed when a particular manufacturer host system, docking cable of the particular manufacturer and I/O device of the particular manufacturer are connected. In certain embodiments, the negotiation of the higher power mode of operation prevents other manufacturer's devices from accessing the higher power when connected to the particular manufacturer's power delivery devices.
